Parameters obtained by fitting the experimental spectra with the equivalent circuit.

Solution	𝑅s/Ohm	𝑅ct/Ohm	𝑌0/μFs^n−1	n
(A) m(HEEDAI) : m(MPII) = 1 : 9	440	120	33	0.8
(B) m(HEPI) : m(MPII) =1 : 9	549	156	25	0.8
(C) m(HEEDAI) : m(MPII) = 1 : 4	769	340	32	0.8
(D) m(HEEDAI) : m(MPII) = 1 : 1	1209	303	46	0.8

Component of solutions A~D was the same as that in Figure 5.
𝑅_s: serial resistance (resistance of solutions); 𝑅_ct: charge-transfer resistance; CPE: constant phase element; 𝑌₀: constant phase angle element; n: a constant ranging from 0≤𝑛≤1.
